    I'm baffled on this one.

    About a month ago, my iBook stopped chiming at startup.

    Repaired permissions.

    Forced maintenance (sudo periodic daily, weekly, monthly).

    Updated prebindings.

    Zapped PRAM.

    Still no chime.

    Any idea on what gives?

    Thanks in advance. :)

    This might sounds like an obvious question, but is the volume turned on?

    Yeah, if the volume in OS X is set to mute then the chimes don't sound either.

    ;) Always a good question to start with - yes the volume is on.

    Does it work perfectly apart from that?

    Sure does - I'm not even sure what the chime REALLY means anyway. :confused:

    The chime basically means that everything is fine as far as the motherboard, etc. are concerned. If everything is working, I wouldn't be concerned. Now if you hear the dreaded shattered glass sound, then I'd start worrying...

    what's PRAM? is this something you should be 'zapping' often?

    It stands for "parameter access memory" - it basically store a lot of preferences that are accessed on bootup.

    You "clear" os "zap" PRAM by holding down CTRL-ALT-P-R down at the same time during boot up until you hear the chime for the second time.
